Detection of Mycobacterium tuberculosis by Using Loop-Mediated Isothermal Amplification Combined with a Lateral Flow Dipstick in Clinical Samples

Table 2

Clinical double blind samples identified with LAMP-LFD, tested with specific carrying the IS6110 gene probes for genotyping, and compared with the culture and AFB smear test.

Culture test*	AFB smear test*				LAMP-LFD test

		Positive		Negative
Positive (93)		75		18	92	1
